Two PAX attendees in Fallout cosplay thought they might be able to trade in months' worth of bottle caps savings for some cool swag at Bethesda's booth in Seattle this past weekend.

Little did Alisha, Trevor's girlfriend of three years, know what was hidden inside the ammo box the Bethesda booth representative handed them. Skip ahead to roughly 3:50 if you want to get to the proposal action. Kudos to Trevor and Bethesda for the very sweet, sneaky moves.
